One hundred and seventy-eight Hereford heifers have been trucked 3,400 km from a Northern Territory cattle station to sale in Tamworth in north-west New South Wales.

Bred at Mount Riddock, a 2,600 square kilometre cattle station, 200 kilometres north east of Alice Springs, the Herefords have spent the last two months on agistment at Walcha, near Tamworth.

Their owner, Steven Cadzow, was standing by his cattle as the bidding started at the Tamworth Regional Livestock Exchange.

He watched on as the 178 heifers, weighing between 230 and 300 kilos, sold in six pens, for between $950 and $980 a head.

Landmark selling agent Scott Simshauser said it was a good result.

"On a cents per kilo basis, that's very good, " he said.

Mr Cadzow said it was not a bad outcome.

"On the day, it's a good price. Can't complain."

Asked if it was worth his while trucking the cattle the large distance, Mr Cadzow said "Yes and no — it's putting our name out there and people have seen what we grow and hopefully we'll get a spin-off."

Three of six lots for sale, a total of 94 head, were bought by north-west NSW Hereford breeder John Hurley.

Mr Hurley, from Wallabadah, said the cattle would be used as breeding stock at his son's property in Goondiwindi, Queensland.

"He's tickled pink. I rang him after the sale," he said.

"They're all going to be artificially inseminated in the next few months to Vena Park Jackpot, the top bull in the Hereford world.

"So we'll do the hybrid cross between the poll Hereford and the Hereford."

Mr Hurley became emotional when asked about the significance of his purchase.
